[Milestone 
Overview](https://gist.github.com/ahmetsait/10925a246b0d412a698e927658f3f363#milestone-overview)

Hi,
This week I've been mostly reading & learning about name mangling 
from the [language 
spec](https://dlang.org/spec/abi.html#name_mangling), [official 
blog](https://dlang.org/blog/2017/12/20/ds-newfangled-name-mangling/) and the
[DMD's source](https://github.com/dlang/dmd/blob/master/src/dmd/dmangle.d).

I've implemented parsing an additional command line switch 
`-mangle-suffix` to get my hands dirty with hacking on DMD 
codebase (see [my mangle-switch 
branch](https://github.com/ahmetsait/dmd/tree/mangle-suffix)). 
Admittedly, it wasn't exactly productive since I had summer 
school finals but I have a lot more time available in these 
upcoming weeks to compansate.

Next week I plan to experiment with mangling code to see where 
can I get in implementing the `-mangle-suffix` semantics.
```d
//app.d
module app;
int foo(int x)
{
     return x * x;
}
```
Above code currently produces a `_D3app3fooFiZi` symbol when 
compiled. The idea is to make it `_D3bar3app3fooFiZi` if 
`-mangle-suffix=app.d:bar` is passed.

I'm checking out https://wiki.dlang.org/DMD_Source_Guide for now 
but it seems somewhat outdated, hopefully the community here can 
endure me bombarding them with questions about DMD codebase.

Thanks.

suffix or prefix? "bar" seems to prefix at least some part of the 
existing name but it doesn't look like a suffix to me. :)

Since it's not strictly a prefix either, perhaps 'affix' or even 
'tag' would be better.
